In this paper, the hydrodynamic and surrounding flow field characteristics of fouled nets panel are studied based on numerical and experimental methods. The types of fouled nets panel are analyzed and be divided into shell aggregation fouled net and bio-accumulation fouled net according to the attachment location and morphological characteristics of contaminants. Physical models of each type of fouled nets panel are made manually for water tank experiments. The corresponding numerical simplified model was established using the large eddy simulation method for flow field simulation to calculate and analyze the hydrodynamics of the net, capture the subtle changes in the flow field caused by pollutants, quantify and analyze the permeability of each hydroid-fouled nets.

本文基于数值和实验方法研究了污垢网板的水动力和周围流场特性。对污染网板的类型进行了分析，根据污染物的附着部位和形态特征，将污染网分为贝壳聚集性污染网和生物累积性污染网。每种类型的污染网板的物理模型都是手动制作的，用于水箱实验。利用大涡模拟方法建立相应的数值简化模型进行流场模拟，计算分析网的流体动力学，捕捉污染物引起的流场的细微变化，量化分析各水螅污染网的渗透率。
